Well, here comes the first of many questions, I can't promise you they will all be intelligent
After a period without photography, I've finally decided to go digital and got myself an a700 last week. The main reason for buying Sony was that I have a Minolta Dynax 800si and Dynax 7 in my cupboard along with 5-6 lenses that I by a stroke of luck heard would fit a Sony DSLR. The chap in the camera shop told me though that I would have to add 50mm to the focal length of my old lenses??? That for example my Sigma Ex 105mm would now work as a 155mm lens on a DSLR. Why do I gain this additional focal length? It would seem a benefit for most lenses apart from my wide-angle lens. The one I have is 17-35mm, but I can definitely see that that's not what it is on the a700. The a700 came with an 18-70mm lens, which certainly visually appears to cover the range of my old wide angle lens, so is the latter of any use to me now? What about aperture? Does the f-stop of a lens remain the same?
